The period of a wave can be calculated using the formula:
Period (T) = 1 / Frequency (f)
Since the speed of the wave is given as 2 m/s and the wavelength is 0.4 meters, we can calculate the frequency as:
Frequency (f) = Speed / Wavelength
f = 2 m/s / 0.4 m
f = 5 Hz
Now, we can find the period of the wave:
Period (T) = 1 / 5 Hz
T = 0.2 seconds
Therefore, the correct answer is:
0.2 seconds
